The objective of DQO Step 1 is to use the information gathered from the DQO scoping process, as well as other relevant information to state the problem to be resolved clearly and concisely. The free-form text sections included in this step are intended to define the task objectives and assumptions, present the task issues, summarize the site background information, and provide a concise statement of the problem. The tables provided in this section are designed to document the personnel involved in the DQO process, identify the contaminants of concern, and summarize the key information needed to support the writing of the problem statement. 1.1 PROJECT OBJECTIVES [Note on completion of Section 1.1: Clearly state the task objectives as they pertain to remediation activities. Begin discussing the task objectives on a large scale, then focus the discussion on the site-specific objectives.] 1.2 PROJECT ASSUMPTIONS [Note on completion of Section 1.2: Clearly state all of the task-specific assump- tions that have been made based on DQO Team discussions and interviews with the regulators.] 1.3 PROJECT ISSUES 1.3.1 Global Issues [Note on completion of Section 1.3.1: Present the date when the global issues meeting was held, and note the organizations that were represented at the meeting. List each of the global issues that were discussed and the resolutions that were agreed upon.] © 2001 by CRC Press LLC A-10 SAMPLING AND SURVEYING RADIOLOGICAL ENVIRONMENTS 1.4 EXISTING REFERENCES Table 1-1 presents a list of all of the references that were reviewed as part of the scoping process, as well as a summary of the pertinent information contained within each reference. These references are the primary source for the background information presented in Section 1.5. 1.5 SITE BACKGROUND INFORMATION [Note on completion of Section 1.5: In this section, provide background infor- mation about the site under investigation. This information will be used to support the development of the problem statement. This section should address the following key areas: • Site description • Site history • Specific areas within the site to be investigated • Summary of all recorded spills and releases • Summary of historical analytical data.] 1.6 DQO TEAM MEMBERS AND REGULATORS Individual members of the DQO Team were carefully selected to participate in the seven-step DQO process based on their technical background to provide expertise in all of the technical areas needed to meet the task objectives. The regulators included representatives from the [Note: Insert the name of the regulatory agencies]. The role of the regulators was to make final decisions related to the sampling design. Tables 1-2 and 1-3 identify each of the individual members of the DQO team and the regulators. These tables also identify the organization that each DQO team member or regulator represents, as well as their technical area of expertise and telephone number.
